Yii2使用$this->context获取当前的Module/Controller/Action
使用Yii2的时候,在某些场景和环境下需要获得Yii2目前所处于的module(模型)、Controller(控制器)、Action(方法),以及会调用控制器里面已经定义过的一些公共的方法等.对于这些问题Yii2可以在视图层View中使用$this->context这个对象去获得。

示例:譬如现在(视图层登陆界面)login.php方法下面：
<?php
//得到Yii2的当前的控制器Controller
echo
$this->context->id;
//输出结果:site
//得到Yii2的当前的控制器Action
echo
$this->context->action->id;
//输出结果:login
//得到Yii2的当前的控制器Modules
echo
$this->context->module->id;
//输出结果:basic
(默认简单的Basic)
//得到Yii2的当前的控制器里面的方法
echo
$this->context->actionHello();
//输出结果:Hello
World!!!
//此处的actionHello()
方法为定义在控制器里面的方法(也可以是继承来的)
//所在位置为SiteController里面,用于测试
public
function
actionHello(){
return
'Hello World!!!';
}
?>
在控制器里面
$controllerID = Yii::$app->controller->id;
$actionID = Yii::$app->controller->action->id;
